Table of Contents
October is for open source. This Hacktoberfest, we’re inviting developers, writers, and designers to help shape the Dodo Payments ecosystem. Our Billing SDK, Customer Portal, Storefront, framework adapters, plugins, developer demos and documentation. Whether you ship a one-line fix or a full new adapter, your contributions will power thousands of SaaS and AI products around the world.
Contributions can be small or large, experimental or production-grade. Every improvement, clearer docs, a new example, a bugfix in an SDK helper lowers integration friction for teams building on top of Dodo Payments.
Hacktoberfest Projects: Billing SDK, Customer Portal, Storefront, Adapters, Checkout Demos,, and Docs
Dodo Payments makes it easier for SaaS, AI, and digital businesses to launch and scale globally: subscriptions, one-time charges, usage-based and outcome-based billing, tax handling, payment methods, checkout flows, and more. For Hacktoberfest we’re focused on plumbing, examples, and docs that make the developer experience better and faster:
Billing SDK: Modern, typed client libraries and helpers so teams can integrate Dodo quickly and idiomatically.
Customer Portal: Merchant-facing portal for subscriptions, invoices, license keys, and billing profile.
Storefront: Customer-facing storefront for product listings and checkout hand-off to Dodo; built with Next.js, shadcn/ui, and Tailwind.
Adapters & Plugins: Drop-in integrations for popular frameworks, CLIs, and tooling.
Checkout Demos: Realistic, copy-pasteable examples that show one-time, subscription, and metered flows.
Docs & Guides: Crisp, friendly documentation and migration guides that remove friction for developers and operators.

Major contributors will receive limited Dodo “Tracks” swag packs: t-shirts, caps, and stickers. We’ll share the design preview on our socials and this post soon.
How we pick recipients (transparent and fair):
Impact: Is the contribution used by developers or merchants right away?
Completeness: Are there tests, docs, and examples?
Collaboration: Was the contributor responsive in reviews and helpful in discussion?
Scope: Multiple small PRs or one large, well-scoped PR, both count.
We’ll also maintain a Hall of Fame and give shout-outs across our channels. [Swag preview will appear in the repo and our social channels.]
